12 . A method of dissecting a tissue specimen inside of a peritoneum of a patient, comprising: providing the outer bag according to claim 1 ; introducing the outer bag through the opening defined through the abdominal wall of the patient; disposing the tissue specimen within a volume defined by the outer bag; pulling the open end of the outer bag through the opening defined through the abdominal wall of the patient with the remainder of the outer bag being disposed within the peritoneum of the patient; inserting the peripheral sleeve through the opening defined through the abdominal wall while retaining the proximal end of the peripheral sleeve outside of the patient, the peripheral sleeve being disposed radially inwardly with respect to the outer bag; coupling the rolling ring to the continuous circumferential edge of the peripheral sleeve; everting the rolling ring from (i) a first orientation, where the rolling ring engages a first region of a proximal portion of the peripheral sleeve, to (ii) a second orientation, wherein the rolling ring engages a second region of the proximal portion of the peripheral sleeve, the second region being located distally along the peripheral sleeve with respect to the first region; rolling the peripheral sleeve about the rolling ring to apply tension to the peripheral sleeve to help stabilize the opening defined through the abdominal wall; and dissecting a tissue specimen while the tissue specimen is located within the peritoneum and within the volume defined by the outer bag; and removing dissected portions of the tissue specimen from the patient through the opening defined through the abdominal wall.
13 . The method of claim 12 , wherein everting the rolling ring includes rotating at least a portion of the rolling ring about a poloidal direction.
14 . The method of claim 12 , wherein the outer bag is introduced into the patient using an elongate tubular body that removably receives the bag.
15 . The method of claim 12 , further comprising enlarging the opening defined through the abdominal wall to facilitate dissection of the tissue specimen.

Each of the foregoing patent applications is hereby incorporated by reference herein for any purpose whatsoever. TECHNICAL FIELD Various aspects of the present disclosure relate generally to surgical devices and methods. More specifically, the present disclosure relates to tissue extraction devices and related methods for minimally invasive surgery. BACKGROUND Conventional tissue extraction devices, such as laparoscopic morcellators, may include a sharp spinning blade for cutting tissue. Such devices may be inefficient and may require prolonged operating times, resulting in increased cost. Such devices also may cause unintended injuries. In some instances, conventional laparoscopic morcellators have the potential to spread occult malignancy, and this may worsen patient prognosis. Improving the design and operation of tissue extraction devices may address one or more of the aforementioned issues. SUMMARY Aspects of the present disclosure relate to, among other things, tissue extraction devices and related methods. Each of the aspects disclosed herein may include one or more of the features described in connection with any of the other disclosed aspects. It may be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the features claimed. As used herein, the terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements does not necessarily include only those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. The term “exemplary” is used in the sense of “example,” rather than “ideal.” The disclosure provides, among other things, embodiments of a kit that in turn includes a bag having a proximal portion and a distal portion, and a retractor ring separate from the bag. The retractor ring can be configured to be coupled to the proximal portion of the bag, and when coupled to the proximal portion of the bag, the retractor ring can be configured to be manipulated from (i) a first orientation, where the retractor ring engages a first region of the proximal portion of the bag, to (ii) a second orientation, where the retractor ring engages a second region of the proximal portion of the bag, the second region being distal to the first region, to pull the distal portion of the bag toward the retractor ring. In some implementations, the retractor ring can include an inner ring and an outer ring, the inner ring being received in the outer ring. The outer ring can include a plurality of discrete segments. The outer ring can be more flexible than the inner ring. The outer ring can be rotatable relative to the inner ring in a poloidal direction of the retractor ring. The retractor ring can be configured to be coupled to the proximal portion of the bag by clamping the proximal portion of the bag between the inner ring and the outer ring. One of the inner ring and the outer ring can include a protrusion complementary to a recess in the other of the inner ring and the outer ring. The retractor ring can be configured to be coupled to the proximal portion of the bag by at least one of a hook and an adhesive. The proximal portion of the bag can include a channel configured to receive the retractor ring to couple the retractor ring to the proximal portion of the bag. The disclosure provides, in some aspects, embodiments of a method of applying tension to a distal po
